Home Performance with Energy Star Program
Home Performance with Energy Star is a national program designed to bring your home up to Energy Star standards. An assessment of your entire home by a certified contractor will show you ways to save on your energy costs.
Many homes built before 1985 are not well-insulated. If you think you need more attic insulation, check our charts for savings, costs, payoff and rebate amounts, found on the Rule Your Attic page. Your certified Home Performance contractor will check the levels of insulation in your walls, floors, attic and rim joists.
Improving heating and cooling systems
If your furnace or air conditioner is more than 10 years old, it’s probably time to replace it with a more efficient unit that is properly sized for your home.
Sealing air leaks
Many air leaks in homes are fairly obvious, such as around windows, doors, and electrical outlets. But others, like those in attics, around chimneys, and through recessed lighting fixtures, are often significant sources of energy loss in a home.
Many homes have leaky ductwork and poor air flow, resulting in stuffy and uncomfortable rooms. Your certified Home Performance contractor may recommend sealing and/or insulating your home’s ductwork along with balancing the duct system to optimize air flow.

The Home Performance program connects each homeowner with a certified Home Performance contractor, who will walk you through the steps of participating in the program.
To participate in this program, please contact several of our certified contractors and ask for a cost estimate before deciding on whom you want to use. For a list of certified contractors, visit our Approved Contractors page.
The assessment can cost from $200 to $400. The cost of the assessment can be financed with our low-interest loan program.
The assessment usually takes about four hours and will provide you with the recommended energy efficiency improvements, the expected energy savings and a rough estimate of the costs to make the upgrades. The contractor will also review your eligibility for rebates.
If you want to apply for a loan, complete and submit the opens in a new window loan applicationopens PDF file to Columbia Water & Light. Wait for approval before starting your upgrades. The loan qualification period takes six months.
Complete all of your energy efficiency improvements.
Make copies of all the invoices for your efficiency upgrades. If you are completing the energy efficiency upgrades yourself, please save the receipts for all the materials. Columbia Water & Light will need copies of them to process your rebate.
Set up an appointment with the Home Performance contractor for a final inspection. At this appointment, a Columbia Water & Light staff member will collect all the copies of the invoices. Your rebate application will be completed at this meeting and turned in for processing.
If you are approved for a loan, you will be contacted two weeks after the final inspection to arrange an appointment for the loan signing papers. Loan checks will either be mailed or given to you at your loan appointment. Your monthly payment for the loan will be added to your utility bill from the City of Columbia.
You will receive a FREE energy efficiency score certificate for participating in the program! The official certificate will show you, and potential buyers of your home, the value of your energy efficiency upgrades.
